Camera module and electronic equipment

Abstract

The invention provides a camera module and electronic equipment. The electronic equipment comprises the camera module. The camera module comprises a lens assembly, a shell, an air inlet, an air outlet and a circulation channel. An opening is formed in the top of the shell; the lens assembly is installed on the shell; the object side face of the lens assembly is close to the opening and is used for receiving light emitted from the opening; the shell comprises a surrounding part; the surrounding part is located at the top of the shell and surrounds the opening; the air outlet is formed in the surrounding part; the air inlet is formed in the outer side face of the shell; the circulation channel is arranged between the lens assembly and the shell and is communicated with the air outlet and the air inlet; an air guide structure is arranged on the circulation channel or the air inlet and used for guiding external airflow into the circulation channel and forming airflow at the air outlet. According to the camera module provided by the invention, active exhaust is realized through the air guide structure, and the camera module can adapt to more application environments.

Description

technical field [0001] The invention relates to the field of camera modules, in particular to a camera module and electronic equipment. Background technique [0002] The on-board lens is placed on the outside of the vehicle and is easily polluted by impurities such as water or dust. Especially in rainy days, rainwater covers the lens and affects the shooting effect of the camera module. In the prior art, the impurities on the surface of the lens are blown away by the airflow generated during the driving of the vehicle to achieve the effect of water and dust removal. However, when the vehicle stops, the effect of preventing rain, water and dust is lost, and it cannot be applied to various application scenarios. Contents of the invention [0003] The purpose of the present invention is to provide a camera module. The camera module includes a lens assembly, a casing, an air inlet, an air outlet and a circulation path. Wherein the top of the casing has an opening, the lens a...
